Chemotherapy and Your Mouth

If so, this information can help you. While chemotherapy helps treat cancer, it can also cause other things to happen in your body called side effects. Some of these problems affect the mouth and could cause you to delay or stop treatment.

This information will give you ways to help prevent mouth problems so you'll get the most from your cancer treatment.

A dentist can help prevent mouth problems.

Chemotherapy is the use of drugs to treat cancer. These drugs kill cancer cells, but they may also harm normal cells, including cells in the mouth. Side effects include problems with your teeth and gums; the soft, moist lining of your mouth; and the glands that make saliva (spit).

It's important to know that side effects in the mouth can be serious.
 

• The side effects can hurt and make it hard to eat, talk, and swallow
• You are more likely to get an infection, which can be dangerous when you are receiving cancer treatment
• If the side effects are bad, you may not be able to keep up with your cancer treatment. Your doctor may need to cut back on your cancer treatment or may even stop it.
   

You may have certain side effects in your mouth from chemotherapy. Another person may have different problems. The problems depend on the chemotherapy drugs and how your body reacts to them. You may have these problems only during treatment or for a short time after treatment ends.

You can see or feel most of these problems. Check your mouth every day.

You may be surprised that your dentist is important in your cancer treatment. If you go to the dentist before chemotherapy begins, you can help prevent serious mouth problems. Side effects often happen because a person's mouth is not healthy before chemotherapy starts. Not all mouth problems can be avoided but the fewer side effects you have, the more likely you will stay on your cancer treatment schedule.

You need to see the dentist at least two weeks before chemotherapy begins. If you have already started chemotherapy and didn't go to a dentist, see one as soon as possible.

You can do a lot to keep your mouth healthy during chemotherapy. The first step is to see a dentist before you start cancer treatment. Once your treatment starts, it's important to look in your mouth every day for sores or other changes. These tips can help prevent and treat a sore mouth:

• Choose foods that are good for you and easy to chew and swallow
  
  
• Take small bites of food, chew slowly, and sip water with your meals
  
  
• Eat soft, moist foods such as cooked cereals, mashed potatoes, and scrambled eggs
  
  
• If you have trouble swallowing, soften your food with gravy, sauces, broth, yogurt or other liquids

Sipping liquids with your meals will make eating easier.

• Work with them to find medicines to help control the pain
  
  
• If the pain continues, talk to your cancer doctor about stronger medicines

Chemotherapy causes other side effects in children, depending on the child's age.

Problems with teeth are the most common. Permanent teeth may be slow to come in and may look different from normal teeth. Teeth may fall out. The dentist will check your child's jaws for any growth problems.

The dentist will check your child's mouth carefully and take out loose teeth or those that may become loose during treatment. Ask the dentist or hygienist what you can do to help your child with mouth care.

Your child has special dental needs.

• Visit your dentist before your cancer treatment starts
  
  
• Take good care of your mouth during treatment
  
  
• Talk regularly with your cancer doctor and dentist about any mouth problems you have

Call your cancer doctor or dentist if you
have any mouth problems.
